This invention relates to an improvement in barricades or bulkheads, forfreight car loadings, of the type shown in my application Serial No.670,178, filed May 16,, 19%, now abandoned.

One of the objects of my invention is to provide a bulkhead or barricadeof the type shown in the above-entitled application, in which not onlythe cross strips or straps between'the frame members are formed ofmetal, but all parts of the bulkhead are formed of metal.

Another object of my invention is the provision of improved means foranchoring the bulkhead by wedging or jamming between the sides of a caror carrier, all, or substantially all, of such anchoring means beingcarried by the bulkhead.

A still further object of my invention is to p ov de a bulkhead orbarrier w en positioned again t a l ad in a carrier and we ed bet ee thewalls thereof. Shocks or the load a ainst the barrier will increase thejamming of the barricade between sides of the carrier.

Having now described, in a general way, the nature and purpose of thisinvention, I will proceed for illustrative purposes, to a detaileddescription of a preferred embodiment thereof, with reference to theaccompanying drawings in which:

Fig. 1 is a face view of one form of bulkhead in accordance with myinvention;

Fig. 4 is a detail face view of the right hand end of the upper railwith a portion in section;

Fig. 5 is a sectional view of the line 5-5 of Fig. 4 on a larger scale;i

Fig. 6 is a sectional view on the line 6-6 of Fig. 3;

Fig. 7 is a perspective view of the lower end of; a side frame memberwith a securing foot welded thereto; J

Fig. 8 is a face view of a modified form similar to Fig. l;

Fig. 8A is a top plan view of the structure shown in Figure 8; and

Fig. 9 is a face view of one of the lower corners of the structure shownin Fig. 8 with portions in section.

Referring to the form shown in Fig. 1 of the drawings. the bulkheadcomprises a frame formed o upper and l we horizontal rails A. nd verticasupports B. B, to wh ch the ends of the rails are welded The rails A, A.a d the ve t col 8 nports B. 3. are for. .d of channel sections. w th teir flanges ext ndi owerds each other with. t e webs on. the outer facthereof- Welded to a rail member- A and vertical support at each cornerof the frame is an angular strut or brace C, which not only reinforcethe frame. against corner stresses, but reinforce the intermediateportions of the rails A, A and supports B, B, against bending stressescaused during the application of straps extending from member to memberduring the tensioning thereof when securing them to the members A, A andB, B as hereinafter described.

Welded to each vertical support 13 is a handle D, and b is a skid platewelded to the bottom thereof thus providing easy handling means as thecar loaders can grasp the handles and slide the structure on the skidplates.

The rails are preferably cambered as shown in Fig. 1A to provide convexfaces adapted to be engaged by the freight when the bulkhead ispositioned in a car against the freight to be held thereby. I

Welded to one flange of each rail A and one flange of each support B onthe freight engaging side of the bulkhead are spaced eyes Ill.Transverse metal strips or straps I2 are connected to the opposite eyeson the supports B, the ends thereof being secured to the body of thestrip by clips l4, and 16 are similar strips connecting opposite eyes Itextending from the rails A, A which are interwoven with the strips l2.

Mounted at each junction of a rail .A and a support B is a screw jackhaving a nut I8, preferably secured to the flange of the rail, oppositethe flange to which the eyes Ill are attached. Threaded in the nut ofeach jack is a screw l9 having a shoulder 20 provided with openingsthrough which a headed actuating lever 21 freely extends, and is alsoprovided with a head 22 at the end of a neck extending from the shoulderin axial alignment with the screw [9. The head 22 is rotatably mountedin a tubular member 28 extending from a plate 23* provided with spursextending from the outer face of the plate for the purpose hereinafterdescribed. The end of the tubular member 23 is provided with an annularflange between the head 22 and shoulder 20 and forms an abutment againstwhich the head bears when the bulkhead is positioned in a car as well asretains the plate 23 on the head.

If desired, a plate such as 23 may be secured to one support B in theplane of a rail A. and both the upper portion and lower portion of theframe secured in position by jacks at the other side of the frame.

When positioning a bulkhead in a freight car after the same has beenloaded, the bulkhead is positioned in front of the load with the bowedside of the rails A, A in contact with the load. The bulkhead is thenforced against the load and the jacks are manipulated to embed the spursinto the Walls of; the car and press the pla es 4 agains he Walls. thery firm y i mming the bulkhead between the walls of the car.

After the jacks have secured the bulkhead in position, the actuatinglevers 2! will drop by gravity as shown in Fig. 1, the weight of thelevers will prevent the screws 19 from being turned by vibration andthus tending to turn the screws of the jacks.

In the structure shown in Figs. 3-7 of the drawings the frame of thebulkhead is also formed of upper and lower rails A, A and supports B, B,all formed of channel sections, the flanges of the supports being spreadto form seats for the reception of the rails A, A, the outer faces ofthe webs of the rails A, A are seated against the inner faces of thewebs of the supports B, B. After the frame members are positionedrelative to each, the flanges of the supports B, B are welded to theflanges and webs of the rails A, A whereby a rigid frame structure isprovided.

Before the frame members are secured to each other, the rails A, A arealso cambered as shown in Fig. 1A so as to curve the outer faces of thewebs of the rails A, A to bow them outwardly to provide convex faces tobe positioned against the load to be secured by the bulkhead. The frameis also provided with four corner braces C, formed of angle sections,the ends of which are welded to the flanges of the rails A, A andsupports B, B so positioned that a broad face of one of the flanges ofeach brace is substantially in the plane of the faces of the webs of therails A, A and supports B, B, thus broad faces of all of the framemembers face the freight to be retained by the bulkhead.

Welded to the outer face of each of the inner flanges of the rails A, Aand the supports B, B

.are spaced eyes H], which are substantially in the plane of the webs ofthe channel sections forming the frame.

After the frame members are secured to each other, transverse straps 12are connected to the eyes In on the side supports 13, B. The verticalstrips I6 are passed through eyes I0 on rails A, A. and are interwovenwith the transverse strips [6 as in Fig. 1.

In order to retain the lower ends of the sup;- ports B, B against thefreight, I may provide a chock formed of a wooden block 24 adapted to bespiked to the floor of the car, and secured to the lower end of eachsupport A is a skid plate 26 having an opening positioned to match oneof the spike openings in the chock 24, or the plate may be naileddirectly to the floor of the car.

In order to secure the upper end of the bulkmeans comprises a wall plate28, provided on itsrear face with a plurality of spurs, which are driveninto the side of the car and the plate is then fixedly secured by lagscrews extending through openings in the plate. Pivotally secured to thefront face of the plate 23 by means of an eye 30, is a hook 32, which isengaged by one of the links of a chain 34 connected to the upper portionof a support B to hold the bulkhead against movement by the freight.

The other securing means may also be considered as a wedge actuated jackwhich comprises a bolt 36, slidably mounted within the recess formedbetween the web and flanges of th upper frame rail A, and is retainedtherein by means of a plate 38 welded to the flanges of the rail. Thebolt is formed of a channel section, the

flanges slidably engaging the flanges of the rail A. The forward end ofthe bolt has a plate it welded thereto and is provided with spurs whichare driven into the wall of the car. The rear end of the bolt is adaptedto be engaged by a wedge 42 seated in slots in the flanges of the upperrail member A. The wedge is provided with a plurality of openings 43 forthe reception of a pin 44 for securing the wedge in its adjustedposition. Both the wedge 42 and pin 44 may be connected to the bulkheadby means of a chain (not shown) to prevent loss, when the bulkhead isnot in use. The web of the channel section forming the bolt is providedwith a slot 46, and 48 is a screw extending through the plate 38, theslot 46 and is threaded into the web of the rail A. This arrangementpermits sufficient movement of the bolt for securing the bulkhead in thecar and freeing the bolt from the car when removing the bulkhead whilepreventing the removal of the bolt from rail A.

Both sides of the upper end of the bulkhead are provided with bothdescribed means for anchoring, or securing, the bulkhead against thefreight.

It will be appreciated that if desired the lower rail member A may beprovided with bolts, such as 36, for securing the ends of the lowerrails of the frame to the sides of a car.

In Fig. 3, I have shown a bulkhead in relation to a portion of a freightcar in dot and dash lines, the vertical lines X designating the sides ofthe door jamb While the lines Z designate the edges of the floor in thedoorway.

Assuming that one end of the car has, been loaded with freight up to apoint slightly back from the edge of the door to provide sumcient spacefor the plates 40 on the bolts 36, the bulkhead is positioned on thefloor and the lower ends of the frame members B, are engaged by thechocks 24, and the bulkhead is moved back against the freight by movingthe chocks over the floor of the car, and when positioned the chocks arespiked to the floor, or, if the chocks are omitted, the plates 26 may bespiked to the floor. Pressure is then applied to the upper frame memberor rail A, to force the portions of the bulkhead between the lower andupper rails A, A, against the freight, and while held in such position,the bolts 36 in both ends of the upper frame rail A, are drivenoutwardly by the wedges 42 to force the spurs on the bolts 36 into theside walls of the car, and when driven home the pins 44 are inserted inholes in the wedges just below the rail A, to prevent upward movement ofthe wedges by vibration of the bulkhead.

If both rails A, A are provided with bolts as shown in Fig. 3, or jacksas shown in Fig. 1, it may not be necessary to secure the supportsto thefloor of the car in a great many cases which may be determined by theload to be barricaded.

After the bolts have been locked against the sides of the car, thechains 34 may be secured to the hooks 32 on the plates 28, secured tothe sides of the car.

If desired, the bulkhead may be provided-with only the bolts, or onlythe chains and hooks (for anchoring the upper ends of the bulkhead.

It will be appreciated that the rail A, A, may be formed of channelsections as shown in the drawings, while the vertical supports B, B, maybe formed of angle sections, one flange being flared and welded to theouter faces of the rails, so that the channel sections may be'used toform uides for the anchoring bolts.

If desired, all of the frame-forming members of either form of bulkheadmay be constructed of angle shapes, one of the flanges of the verticalsupports B, B being flared to form seats for the top and bottom rails A,A, and tubular members for the bolts may be formed in the ends of therails by welding the edges of the flanges of short angle sections to theflanges of the rails at the ends thereof for form shown in Fig, 3.

The structure in Figs. 8 and 9 differs from Figs. 1 and 1A only in theconstruction of the jack and that the channel sections A, A and B, B ofthe frame in Fig. 8 are positioned at right angles relative to those inFig. 1 so that the webs of the rails A, A and supports B, B are in theplanes of the straps l2 and I6.

By positioning the rails and supports as shown in Fig. 8, the channelsections resist the strain imposed by the stretching of the straps l2and 16 during their application thereof to the rails and supports thanwhen positioned as in Fig. ll

By positioning the channel sections of the frame as in Fig. 8, themembers need not be braced by struts C, C as in Fig. 1 but can be bracedby gusset plates C which materially reduces the weight of the barricadeas well as the cost. l

The same reference characters have been applied to similar parts inFigures 8 and 9 as applied to the structures shown in Figures 1 and 1A.

The eyes In to which the straps i4 and it are secured in Fig. 8 arewelded to the members A, A and B, B at the junctions of the web and oneof the flanges on freight engaging side of the frame, While the gussetplates C are welded to the flanges of a member A and B on the oppositeside of the frame at each corner thereof.

Welded to each gusset plate C is a nut I8 for a jack in which the screw19 is threaded and is I provided with the usual spherically shaped head[9 the head [9 of the bolt is rotatably mounted in a tubular member 23extending from a plate 23 which is provided with spurs extending fromthe other side thereof. lhe interior of the tubular member is providedwith a spherical socket 9 for the head Is the face of which is closed bya plate 23* which is provided with an opening for the bolt which is ofsufficient diameter to permit the plate 23 to rock on the bolt head toseat the plate against the lining of the car if the bolt should notextend exactly radially from the center of the socket.

The plate 23 and the tubular member 23 are preferably formed of a steelcasting, the bolt is passed through the opening in plate 23' and is thensecured to the end of the tubular member 23, preferably by welding. Theheaded actuating lever 2| is passed through an opening in the end of thescrew 19 instead of through a head formed on a shouldered head on theother end of the bolt.

Such a structure greatly reduces the cost of the jack as well as reducesthe weight of the structure.

One of the advantages of my invention results from the provision of anall metal bulkhead in which the main frame-forming members are formed ofstandard rolled metal sections and which are provided with laterallymovable means carried thereby arranged to be spread to increase thewidth of the bulkhead to engage the sides of a freight carrying.compartment of a carrier such, for example, as a freight car, a freightcarrying truck; or vessel; and retain a load by pressure applied by themovable means to jam the bulkhead between the Walls of the compartment.

Another advantage of my invention results from the positioning of a flatface of each frame member on the face of the bulkhead or barricadewhereby one face thereof is free of projecting portions which mightinjure articles in contact therewith when positioned as a barricade.

Another advantage of my invention results from the provision of abarricade having bowed transverse frame members provided with means forjamming the barricade between the Walls of a compartment whereby, whenpositioned with the concave faces of the transverse frame membersagainst a load, any shock of the load against the barricade will tend tostraighten the frame members and increase the pressure against one ofsaid members between the walls of the compartment.

Another advantage of my invention results from the provision of cornerbraces or struts at the corners of the frame, extending from one mainframe member to another main frame member at right angles thereto, theends of the braces being welded to the main frame members with the broadface of each of the struts in the plane of the broad faces of the mainframe members In the claims, the term car has been used to designate alltypes of freightcarriers or compartments in such carriers.
